Well not to long ago i had ABS problems on the front left side of my 98 blazer. It was prabably due to the bearing wearing down and causing problems with the ABS sensor. So since then i have replaced the hub on the left side, upper and lower ball joints on both sides, and now all 4 tires. Yet i still hear a bit of a hum when driving down the road. The hum will go away if I make a steady right had turn around a curve or something. Before i replaced my tires i thought that might have been the solution but apparently it was not. So it seems suspect that my front right bearing my be going bad? What do you think. I have a 142k miles on the truck.

What did you torque the hubs to?

i dont remember the exact torque i used i want to say like 107ft/lbs or soemthing like that. i got the exact number from a post on here. This problem was around before i replace the first hub. I have only replace the left side hub, and i believe the noise is coming from the right front side.

Could very well be... Be aware though the the proper torque for our hub bearings (and you can confirm this at the dealership) is 180 ft pounds... At 107 you will end up replacing the hub a lot sooner..

actually now that i look back, i think it might have been this post, you posted on here as well. but there was 2 different torque specifications. 103 and 180.

so how does less torque cause more problems than more torque??
